String Instructions. The string instructions facilitate operations on sequences of bytes or words. None of them take an explicit operand; instead, they all work implicitly on the source and/or destination strings. The current element (byte or word) of the source string is at DS:SI, and the current element of the destination string is
Mnemonic: REP. Operation: This is an instruction prefix which can be used in string instructions. It can be used with string instructions only. It causes the instruction to be repeated CX number of times. After each execution, the SI and DI registers are incremented/decremented based on the DF (Direction
21 Dec 2015 16. Data Transfer Instructions : The MOV instruction is used to transfer a byte or a word of data from a source operand to a destination operand. These operands can be internal registers of the 8086 and storage locations in memory.

The 8086 microprocessor supports 8 types of instructions ?. Data Transfer Instructions; Arithmetic Instructions; Bit Manipulation Instructions; String Instructions; Program Execution Transfer Instructions (Branch & Loop Instructions); Processor Control Instructions; Iteration Control Instructions; Interrupt Instructions. Let us now
The String Instructions. Module 11. CS 272. Sam Houston State University Dr. Tim McGuire. String Instructions. A string is simply an array of bytes or words; Here are some operations which may be performed with string instructions. copy a string into another string; search a string for a particular byte or word; store characters
Direction Flag. one of 8086 processor control flags. controls the direction of string operations: DF = 0 => forward (left to right) processing. DF = 1 => backward (right to left) processing.
Strings are usually arrays of bytes, words, or (on 80386 and later processors) double words. The 80x86 microprocessor family supports several instructions specifically designed to cope with strings. This chapter explores some of the uses of these string instructions. The 80x86 CPUs can process three types of strings: byte
String Manipulation Instructions. A series of data byte or word available in memory at consecutive locations, to be referred as Byte String or Word String. A String of characters may be located in consecutive memory locations, where each character may be represented by its ASCII equivalent. The 8086 supports a set of more
